Projects’ Ultimate Provide monthly and annual parameter loadings, as well as unit area loadings in numerous 12 digit HUCs. The long-term goal of the priority watershed program is to reduce pollutants to levels that will restore all designated uses.

Monitoring Structure – Similar activities are implemented in each monitored watershed that support the projects’ primary goal. Water Quality Requirements – Incorporates project design, collection and analytical methodologies to generate representative data and allow for an evaluation of water chemistry within the selected watersheds. Discharge Requirements – Estimate the volume of water that passes the monitoring station during the sampling period. Data Compilation and Statistical Analysis – Compile and statistically analyze the collected data to provide monthly, annual, and unit area loadings, as well as, compare results between monitoring stations. Reporting Requirements – Provide project partners with the project outcomes and make the results readily available to the natural resource professionals and to the general public.

Bayou Bartholomew Watershed Focusing on the Cousart Bayou and Deep Bayou Sub-watersheds The Bayou Bartholomew was included on the Arkansas 2014 303(d) for not supporting designated uses. ANRC has designated the watershed as a priority watershed. NRCS also identified the Bayou Bartholomew as a priority in the Mississippi River Basin Healthy Watershed Initiative.

Lake Conway Point Remove Watershed Primary focus is East Fork and West Fork of Point Removed Creek LCPR scored 91 in the Final Risk Assessment Matrix Percentile of the Arkansas’ Nonpoint Source Pollution Watershed Risk Matrix and has been selected as a priority watershed. NRCS identified LCPR as a priority in the Mississippi River Basin Healthy Watershed Initiative.

Lower Ouachita – Smackover Watershed Focused on the “outfalls” of 12 digit HUC Portions of the Lower Ouachita –Smackover HUC have been included on the Arkansas 303(d) list for not supporting aquatic life and drinking water designated uses and has been on each subsequent 303(d) list. ANRC has designated the watershed as a priority watershed.

L’Anguille River Watershed Focused on the “outfalls” of 12 digit HUC The L'Anguille River was included on the Arkansas 1998 303(d) list for not supporting aquatic life due to siltation/turbidity and has been on each subsequent 303(d) list. ANRC has designated the watershed as a priority watershed. NRCS also identified the L'Anguille River as a priority in the Mississippi River Basin Healthy Watershed Initiative.
